The best person to comment on this is Charles Dodgson. He may, of course, be a pseudonymous member of this forum, but I am sure he will allow me to quote three passages from "Through the Looking Glass" (the first is surely a commentary on hexagonal Aeolas).
`Don't stand chattering to yourself like that,' Humpty Dumpty said, looking at her for the first time, `but tell me your name and your business.'
`My name is Alice, but --'
`It's a stupid name enough!' Humpty Dumpty interrupted impatiently. `What does it mean?'
`Must a name mean something?' Alice asked doubtfully.
`Of course it must,' Humpty Dumpty said with a short laugh: `my name means the shape I am -- and a good handsome shape it is, too. With a name like yours, you might be any shape, almost.
‘The name of the song is called "HADDOCKS' EYES."'
`Oh, that's the name of the song, is it?' Alice said, trying to feel interested.
`No, you don't understand,' the Knight said, looking a little vexed. `That's what the name is CALLED. The name really IS "THE AGED AGED MAN."'
`Then I ought to have said "That's what the SONG is called"?' Alice corrected herself.
`No, you oughtn't: that's quite another thing! The SONG is called "WAYS AND MEANS": but that's only what it's CALLED, you know!'
`Well, what IS the song, then?' said Alice, who was by this time completely bewildered.
`I was coming to that,' the Knight said. `The song really IS "A-SITTING ON A GATE"
`This must be the wood, she said thoughtfully to herself, `where things have no names. I wonder what'll become of MY name when I go in? I shouldn't like to lose it at all--because they'd have to give me another, and it would be almost certain to be an ugly one. But then the fun would be trying to find the creature that had got my old name! That's just like the advertisements, you know, when people lose dogs--"ANSWERS TO THE NAME OF `DASH:' HAD ON A BRASS COLLAR"--just fancy calling everything you met "Alice," till one of them answered! Only they wouldn't answer at all, if they were wise.'
